摘要： PROBLEM TO BE SOLVED: To obtain an undercoat which is hardly influenced by the property of ink to be used when ink jet printing is performed by forming an inorganic coat on a metallic panel with a resin layer formed on the surface of a metallic material and thereby upgrading the adhesive properties of the ink. SOLUTION: A primer layer 2 and a polyester resin 3 are formed by lamination on a galvanized steel plate 1 as a metallic material. Next, a coating liquid obtained by adding nitric acid and ethanol to Si(OC2 H5 )4 and mixing and stirring these materials so that it is about 1 wt.% in terms of SiO2 , is used and spray- coated to the metallic material until the average coat is about 0.5 μm thick in such a state that the metallic material is kept at 50 deg.C. Further, an inorganic coating film 4 is formed on the polyester resin 3 and an arbitrarily selected pattern is drawn by forming ink 6 containing SiO2 particles through the inorganic coating film 4. In addition, an acrylic resin 7 is coated as a clear protecting coating film, on the pattern to protect a printed face against marring.

摘要： PROBLEM TO BE SOLVED: To easily and successively extend the rugged pattern on a plate to be worked at a low cost by filling a large number of spherical balls in a cavity part of a lower die in a movable manner in the horizontal direction, and moving a rod-shaped tool through NC control in the X, Y directions while pressing the tool against the plate to be worked which is fitted to the lower die. SOLUTION: Spherical balls 6 are filled in a cavity part 2 of a lower die 1. The capacity of the cavity part 2 is regulated by moving a regulation plate 5. A plate 7 to be worked is fixed to an upper surface of the lower die 1. An upper punch (rod-shaped tool) 9 is pressed against the plate 7 to be worked through NC control, and a movable table 11 is moved in the X, Y directions. When the upper punch 9 is lowered, the spherical balls 6 on each side of the upper punch 9 support the plate 7 to be worked, and a recessed extending part 10 is formed immediately below the upper punch 9. As the extending part 10 is formed, the position of the regulation plate 5 is controlled to secure the gap through which the spherical balls 6 are moved.

摘要： PURPOSE:To perform a bending of a prescribed angle with one process of bending work, by automatically measuring a bending angle of work on a machine and by feed-back controlling the data on line for the motion (rotating angle of wing pattern) of bending mechanism. CONSTITUTION:A work 22 set in a clamp pattern 25 and a base 2 is bent by means of the rotation of a wing pattern 24 by a cylinder 23. After the wing pattern 24 reached a predetermined wing angle, and after it returned to an original condition, a measuring head 20 advances, and a bending angle error alphais calculated by a controlling device, and the angle error alpha is calculated comparing with standard value so as to give decision on whether or not it is within the allowance. If it is found to be outside of the allowance, the characteristic data on the material considering spring back etc. of the work 22 etc. is modified by the angle error alpha and the bending work is performed again at the commanded value of bending angle for the wing pattern 24 obtained from modified data.
